One-Pan ‘No-Boil’ Dump and Bake Meatball Casserole

  • Total Time: 50 minutes
  • Yield: 68 Servings 1x

Description

The ultimate solution for busy weeknights. By skipping the pasta boiling and combining everything in a single 9×13-inch dish, you create a rich, cheesy, and satisfying dinner with tender rotini, savory meatballs, and a blanket of melted mozzarella.


Ingredients

Scale

The Main Bake

  • 1 box (16 oz) rotini pasta, uncooked
  • 1 jar (24 oz) pasta sauce
  • 3 cups water
  • 1 bag (14 oz) frozen precooked meatballs, thawed
  • 1 tsp kosher salt

The Topping

  • 2 cups shredded mozzarella cheese

Instructions

Prep: Preheat oven to 425°F. Spray a 9×13 dish with nonstick spray.

Dump: Add uncooked rotini, water, sauce, thawed meatballs, and salt to the dish. Stir well.

Bake: Cover tightly with foil. Bake for 35 mins, stirring once halfway through (at ~18 mins) and re-sealing tightly.

Cheese: Remove foil, stir again, and top with mozzarella.

Melt: Bake uncovered for 5–8 mins until cheese is bubbling and golden.

Notes

The Steam Secret: A tight foil seal is non-negotiable; trapped steam is what cooks the dry pasta.

Thaw Your Meatballs: Frozen meatballs release too much moisture and cool the liquid, leading to soggy pasta.

Fresh Shreds: Shred mozzarella from a block for the best melt; pre-shredded starch coatings can inhibit the ‘cheese pull’.
